Straightforward synthesis of isopropylidenediphenylsulfurane and application to industrially viable stereoselective synthesis of deltamethrin insecticide

Abstract

peer reviewedWe describe three stereoselective syntheses of deltametrin, one of the most potent industrially available insecticides, from γ-alkoxy-α,β-unsaturated carbonyl compounds, isopropyldiphenylsulfonium tetrafluoroborate and potassium tert-butoxide
